Supermicro psu and gigabyte motherboard problem

Hi there,

I have a supermicro chassis and redundant power supply, along with a Gigabyte GA-EX58-UD4P mother board, and an i7 920 CPU.

When I go to boot the computer all i get are sort beep which keep going.
Tried powering up with another psu and no beeping.

I did a little more reasearch and started metering the psu outputs. I found that both were identical except that the super micro did not have a -5v line, jsut an empty whole.

Does someone on here have a better idea as to what the deal is with the -5 line? looking at Wikipedia, they suggested that the -5v line is no longer used and is optional....

turns Supermicro motherboards do not require -5v....

Do I have any other options other than going with a supermicro board?

thanks,

-Erik

The ATX 2.0 specifications did away with the -5 volt output.
